l! c czZZ whom it may concern:

Beit known that I, ASA F. BA'roHELDEn., a citizen of the United States, residing at Schenectady, county of Schenectady, State of New York, have invented certain new and useful Improvements in Oar-Trucks, of which the following is a specification.

' My invention relates to ear trucks, and particularly to trucks having an electric rnetor incorporated therein and adapted to drive two or more of the wheels of the truck.

My invention has for an object to provide a simple, substantial and easily constructed truck. In attaining these ends I have so arranged a frame on the side frames of the truck that it serves both as the field frame of the motor and as the bolster upon which the bodyT 'of the car rests. l

lMy invention will be understood from the 2o following description taken in connection withthe accompanying drawings, in which Figure lis a side elevation of a truck having my invention embodied therein; Fig. 2 is 'a transverse cross-section through practically the middle of the truck shown in Fig. 1; Fig.

v3 is a vplan View of the same truck, certain parts being broken away to show the construction; Fig. 4 is a perspective view of one end of the combined bolster and Iield frame casting; and Fig. 5 is a perspective view of .one end of the cover which closes the bottoni of the frame shown in Fig. 4.

The* truck in which I have shown `my invention as embodied has three axles 6, 7 and` 8, upon which are mounted wheels 9, 10 and 11. The axles 6, 7 and 8 ru'n in journal boxes 12 arranged to `slide in the side frames 13 and 14, said-'side frames being supported on said journal boxes by springs 15 and straps 16 in any vsuitable and wellfknown manner. A sheet metal strap 17 may be interposed be# tweenthe ends of the springs 15 and the extended tops of the journal boxes 12 in order to provide a good sliding surface for the ends of the springs, and at the same time to pre# vent the springs from tending to move the journal boxes longitudinally of the frame. The armature 1S .of the driving motor is mounted on the axle 7 in any well-known and suitableinanner.

y AThe side frames 13 and 14-are held apart and in fixed relation to one another by a casting 20; of lthe form shown in Figs. 1 to 4, whicli casting is secured to the upper part of' f the side frames byl lugs 21 and bolts 22, the

, frame of the motor.

lower part of the frame 20 being secured to the bottom of the side frames 13 and 14 by means of lugs 23 bolted to angle-irons 24 bolted to the side frames 13 and 14. This frame 2() extends over the middle pair of wheels, and over and down upon each side of the armature 18.

Integral with and secured to the casting 20 are the pole pieces 26 which are surrounded by the field'coils 27, and it is apparent the ends of which aie'connected by tie rods 33 in a manner well known in thisart, Lugs 34 made integral with the casting 20 have sliding engagementA with the bottom of the car body andserve to help support the same in the usual manner. The castingr 30 serves, therefore, as 'a bolster as well as a motor-field framef 1The lower part of thc frame 2O is closed bymeans of a sheet metal cover 35 which-may be bolted to the part 20 by means of bolts The plate 35 has at one end an up-turned portion 37 which is out out concentric with the commutator of the armature 18 and serves to prevent dirt from working into the armature. On the other end ofthe cover 35. is anup-turnod web 38 which helps to close the other end of the casing formed by the casting 2() and the cover 35. The motor brushes have not been illustrated since they form no part of my in vention. They may be secured in any suitable manner to the inside of the casting 20.

W hlle I have shown but one orm in which is arranged to slide transversely of the ltruck between lugs 31, integral with the casting 20, against the .tenslen of sprmgs'SZ,

my invention may be embodied, I do not vertically, springs for supporting said frames `on said journal boxes, a motor armature mounted on one axle, and a combined bolster and motor iield frame supported on said side framesl 2. In a car truck, a .plurality of Wheels and axles, j ournalv boxes for said axles, side frames in which said journal boxes may move vertically, springs for supporting said frames on said journal boxes, a motor armature mounted on one axle, and a frame supported on said side frames and extending over and down upon each side of said armature and adapted to serve both as a bolster andas a motor ield frame.

3. 1n a car truck, three axles ,having Wheels thereon, journal boxes for'said axles,

` side frames in which said journal boxesmay move vertically, springs for supporting said frames on said journal boxes, a motor armature mounted on the middle axle, and a combined bolster and motel' iield frame supported on said side frames and extending from one to the other over the motor armature.

4. In a ear truck, three axles having Wheels thereon, journal boxes for said axles, side iframes in which said journal boxes may move vertically, springs for supportingsaid frames on said journal boxes, a motor armature mounted 4on the middle axle, and a frame supported on said sidel frames and extending over the middle pair of Wheels and over said armature and down upon each side thereof, said frame being adapted to serve both as a bolster and as a motor eld frame.

5. In a ear truck, 'three axles having Wheels thereon, journal boxes for said axles, side frames in which said journal boxes may move vertically, springs for supporting said frameson said journal boxes, a, motor armature on the middle axle, and a one piece frame supported on said side frames and extending over the vmiddle pair of Wheels and over and down on each side ot' said armature and having pole pieces integral therewith, said one piece frame being adapted to serve both as a bolster and as a motor iield frame.

6. In a car truck, three axles having Wheels thereon, journal boxes for said axles, side frames in Which said journal boxes may move vertically, springs for supporting said frames on said journal boxes, a motor armature mounted on the middle axle, a bolster frame supported on said side frames and lextending over said motor armature and down upon each side thereof, and iield coils supported by said bolster frame and surrounding field poles formed integral with said bolster traine.

In Witness whereof, I have hereunto set my hand this 27th day of January, i908.
